Re: good amp for my two 6x9´s 110W rms JBL P963 @2ohm speakers

They are in the rear powered by a ****** amp.
I have also two 6 1/2 connected to the HU.
And a 12" sub powered by another ****** amp. I bought these two used amps momentarily until I save more money. They are old and have lots of issues.

I was thinking on buying the 4 channel amp, so I can give the 6x9´s 150W RMS and also connect the front speakers or the sub to it, (but I wanted to be sure that the 150W RMS powering the 6x9´s are enough, or if it would be preferable to give them 190W RMS, or the bridged 250W RMS.)
